Clinical Analysis of Ocular Parameters Contributing to Intraoperative Pain During Standard Phacoemulsification

Charts of 142 patients who underwent standard phacoemulsification under topical anesthesia between March and August 2016 were reviewed. The pain during phacoemulsification and 1 h after surgery was assessed and compared using a visual analog scale.

About this study

Patients scheduled for elective phacoemulsification and intraocular lens implantation with the Infiniti Vision System (Alcon, Fort Worth, USA) were included. All operations were performed in Kyungpook National University Hospital by the same surgeon between March and August 2016.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Patients underwent phacoemulsification with topical anesthesia

Exclusion criteria

Patients who needed general anesthesia or were taking medications capable of affecting perceived pain
Patients who had traumatic cataract and/or conditions likely to require vitrectomy and trans-scleral fixation of posterior chamber intraocular lens

Treatment and study plan

phacoemulsification

Device

The device device used to provide and perform small profile entry for cataract extraction with or without option of insertion of a specified intraocular lens implant

Other names: INFINITI® Vision System

Primary outcomes

Pain score assessed with Visual Analogue Scale (VAS)

Time frame: 1 hour after the end of surgery

Visual Analogue Scale (VAS) is a measurement instrument that tries to measure a characteristic or attitude that is believed to range across a continuum of values and cannot easily be directly measured.

A third person assessed subjective pain using a pain visual analog scale ranging from 0 (no pain) to 10 (worst pain imaginable) after surgery.
